The envelope theorem for locally differentiable Nash equilibria of finite horizon differential games 总被引:1,自引:0,他引:1
Envelope theorems are established for a ubiquitous class of finite horizon differential games. The theorems cover open-loop and feedback information patterns in which the corresponding Nash equilibria are locally differentiable with respect to the parameters of the game. Their relationship with extant envelope results is discussed and an application of them to a generalized capital accumulation game is provided. An important implication of the theorems is that, in general, the archetypal economic interpretation of the costate vector, namely, as the shadow value of the state vector along the Nash equilibrium, is valid for feedback Nash equilibria, but not for open-loop Nash equilibria. 相似文献

Informed by Coase's (1988) idea that state rules can enlarge a market, Rosa's (2006) idea of information as a private good usable as memes, and Yu's (1981) economics of patent pooling, Schuster's (2005) proposition that government can collect and distribute information as an active tool to influence actors, this paper advances the viewpoint that real estate development forms sign structures for adding information that enhances the values of a site under strategically selected property names. The ideal case of Hong Kong's planning and development by contract is used and compared to the practice in Mainland China to demonstrate these ideas with special reference to its open land registration and information systems, which sell important information memes and the names of properties that can be protected by trademark law. 相似文献

科斯的工作决不仅仅是对于社会成本问题的一个解答,更为重要的,是他为我们提供了一种透视经济现象的新方法、新视角。这集中地表现在两个方面:其一,用一般均衡的观点看世界;其二,重视约束条件。在一般均衡框架下,在理想的没有“摩擦”的经济环境中,不可能有“对个人来说是对的,”也不会有“对社会整体来说是对的,但对个人来说却不对”的事情。这是科斯定理的另一种表述了。“合成谬误”的传统分析不仅与科斯的新的方法、新的视角相背离,也与科斯定理的基本内涵相矛盾。而“囚犯难题”个人理性与集体理性相冲突的传统分析同样也与科斯的新的方法、新的视角相背离,并与科斯定理的基本内涵相矛盾。 相似文献

This study reports the results of a factor content analysis of the sources of West Germany's comparative advantage in 1976, 1980 and 1984, using highly disaggregated skill variables. The county is found to be most abundant in certain skilled manual occupations and a very limited number of professional and technical occupations. The results differ markedly from those reported in similar studies for the UK and the US. The importance of intercounty productivity diferences and the implications of using only a subset of the economy, i.e. manufacturing, in the calculations are assessed. While using only a subset of the economy might have been appropriate in the past when services trade was relatively unimportant, this is no longer the case, especially for Germany with its diferent performance in goods and services trade. It is argued that the explanatory power of comparative advantage as a basis for trade among similarly developed countries is much higher than is commonly perceived when human capital is disaggregated into detailed skill categories that allow the recognition of different skill mixes between countries. The use of a disaggregated ‘labour-based’ neoclassical trade theory is advocated. 相似文献

文献[9]建立了项目投资关联优化模型,提出了相互等价的定理3和定理6,本文证明了定理3和定理6存在无法判别方案优劣的区间,杨氏定理难以成立;利用文献[9]中的案例进行的实证分析,证明纯经济效益最大化才是互斥方案选优决策的科学准则。 相似文献

This paper proves that for the case of a small country, which cannot influence world factor prices, an expansion in the scope of international factor mobility can never reduce its real national income. [F11, F20] 相似文献
